Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718424, here are decompositions:

5 + 8718419 = 8718424
17 + 8718407 = 8718424
23 + 8718401 = 8718424
47 + 8718377 = 8718424
173 + 8718251 = 8718424
227 + 8718197 = 8718424
233 + 8718191 = 8718424
311 + 8718113 = 8718424

Showing the first eight; more decompositions exist.
